Patent DE-4242810-A1 (DE)
Inventor: KIM JIN-KI
IPC: G11C17/00
Filed: 1992-12-17
Abstract: An electrically erasable programmable read only memory (EEPROM), having error checking and correction circuitry uses a separation circuit to electrically isolate a temporary page buffer memory from a memory array so that better reliability of parity generation and error correction is provided. The EEPROM memory array includes a plurality of bit lines, a plurality of memory cells respectively connected to the bit lines and parity cells. The error check and correction circuit includes a column gate logic, connected to the plurality of bit lines, for temporarily loading randomly input data onto a memory page buffer. The EEPROM processes the data in the page buffer to logically store it as multi-byte data, simultaneously together with appropriate parity bit data corresponding to each multi-byte data set, in the memory array. Because data randomly input to and from the page buffer is selectively, electrically isolated from the memory array, bit errors that would otherwise be caused by defective memory cells, or bit lines, within the memory array, are compensated for in advance.

Title: Toothbrush with mechanical drive
Inventor: BALKAYA AHMET
IPC: A61C17/24
Filed: 1993-02-11
Abstract: Electrically driven toothbrushes consume current, are dependent upon the presence of electrical current, contain expensive electrical components and present ecological disadvantages when thrown away, e.g. due to batteries. Brushing with "normal" hand-held toothbrushes takes too long and is too laborious. The novel toothbrush is to permit easier, quicker and more thorough cleaning of the teeth without any current. The novel toothbrush comprises at least 3 exchangeable, rotating round brushes with obliquely and spirally arranged bristles. This arrangement saves time in that there is brushing by the bristles without any interruptions and the entire dental surface to be cleaned is distributed over several brushes. The bristle arrangement replaces the recommended, circulating bristle movement from "red to white". The handle of the novel toothbrush can be compressed like tongs, and the compressing movement of the hand is mechanically converted to a rotating drive for the brushes. Rotating force and speed of the brushes can be regulated via manual force. The novel toothbrush is intended for use as a worthwhile alternative to the conventional manual and electrical toothbrushes. <IMAGE>
